The nurse cares for a client who takes warfarin for atrial fibrillation (afib). What is the therapeutic INR level?

Correct Answer: A

Rationale: The correct answer is A: INR = 2-3. This range is the recommended therapeutic INR level for clients taking warfarin for conditions like atrial fibrillation. An INR of 2-3 indicates the blood is thin enough to prevent clot formation yet not too thin to cause excessive bleeding. Choices B, C, and D are incorrect because an INR of 2-6 is too high and can increase the risk of bleeding, an INR of 6-3 is inverted and not a standard range, and an INR of 3-3 is not a valid range for therapeutic levels.

Correct Answer: C

Rationale: The correct answer is C because collaborating with a client while developing a nursing care plan empowers the client to actively participate in their own care decisions, respecting their autonomy. This approach ensures that the client's values, preferences, and needs are considered, fostering a sense of control over their healthcare journey. Incorrect choices: A: This option focuses on setting goals for the client without necessarily involving them in the decision-making process, limiting their autonomy. B: While important for client safety, assessing for postprocedural complications does not directly promote client autonomy as it is more focused on the nurse's responsibilities. D: Encouraging independent ambulation is beneficial, but it does not necessarily involve the client in the decision-making process, unlike collaborating on a care plan.

Correct Answer: C

Rationale: Step 1: Subjective data refers to information provided by the client themselves. Step 2: The client stating "I feel nauseated" is subjective data as it comes directly from the client. Step 3: This subjective data is valuable for assessing the client's symptoms and potential health issues. Step 4: Peripheral pulses, skin condition, and bowel sounds are objective data that the nurse can observe or measure. Step 5: Therefore, choice C is correct as it reflects subjective information from the client, aiding in a comprehensive assessment.

Correct Answer: D

Rationale: The correct answer is D: Autocratic. In an emergency situation, quick decision-making and clear direction are crucial. An autocratic leadership style allows for rapid decision-making and immediate implementation of actions, which is essential during emergencies. This style ensures a swift response without the need for lengthy discussions or debates. Laissez-faire (A) would lack the necessary direction and control in a crisis. Democratic (B) may lead to delays in decision-making due to the need for consensus. Transactional (C) focuses on rewards and punishments for performance, which may not be suitable for an emergency where quick action is required.

Correct Answer: A

Rationale: BSN-prepared nurses receive a broader education that includes leadership, research, and public health, unlike the more technically focused ADN.
